Population growth due to migration was dramatically high until the 1990s (9.36) but slowed down thereafter (Table 5-3). However, the increase in population will continue despite the declining growth rate. The opening of many residential subdivisions as well as commercial and industrial establishments in Santa Rosa is expected to attract migrants of working age and child rearing age.
Population Doubling Time
One concept used to explain the implications of population growth rate is the time required for the population to double itself. Using the formula of dt = 0.69 over the population growth rate, the City of Santa Rosa would take about 16 years to double itself, assuming a growth rate of 4.37 percent.
